SEPECIPICATION forming part of Letters Patent No. 340,733, dated April 27, 1886.

Application filed November 24, 1884. Serial No. 148,700. (No model.)

.To (tZZ whom it may concern:

Be'it known that I, LUoIUs RonERTsoN, of Mount Carmel, Olermont county, and State of Ohio, have invented certain new and useful Improvements in Window-Sashes, of which the following is a specification.

My invention has for its principal object the providence of novel and efficacious means whereby the windowsash, with its pane or panes, can be qnicklyswung into the room to be cleaned or repaired, and as quickly and easily replaced in its window-frame, thereby enabling both sides of the sash or panes to be cleaned or repaired without endangering the person cleaning or repairing the sash or panes.

In the accompanying drawings,. making partlofthis specification, Figure 1 shows in perspective awindow sash and frame embodying my improvements. Fig. 2 is a horizontal cross-section through-the line X X of Fig. 1. Fig. 3 is an enlarged cross-section of frame and sash, showing certain details of construction. Fig. 4 shows the details of the form of hinge between the inner sash-piece and one of the slide-pieces of the sash. Fig. 5 is a perspective: showing the rollers of the slidepieces of the sash.

I make the window-sash in three parts, two side pieces sliding in grooves in the windowframe, the third being the frame which incloses or holds the glass, and which is hinged to one of the side pieces and secured to the other side piece by a fastening which can be operated so that this last-named side piece and sash-frame can be connected or disconnected at pleasure.

1n the drawings, B represents that part of the windowframe in which the sash slides. The frame B on each side of the window is provided with two vertical parallel dovetailed grooves, f, one for the upper and the other for the lower sash. The sides of these grooves are usually to be formed by the strips present in window-frames; but the sides of said strips are preferably beveled to make the grooves of a dovetail shape. At the bottom of the groove f is a smaller secondary groove, 7, in the center of which is a third groove, 01, preferably semicircular in section. Metal plates is are set in or on the window-frame, near the bottoms of the grooves f, one plate, It, being on one side of groove 1', and the companion plate 7c being on the other side of the groove f. The plates are preferably located,

as shown, between the strips B and the frame B, and are secured to the strip or to the frame,

or both, in any suitable manner. The sliding side pieces, A, arejsimilar to each other, except as to the differences already mentioned. Each is dovetailed to fit the groove f, and each is preferably provided with two or more rollers or sets of rollers to reduce friction. The preferred arrangement of these rollers is well illustrated in Figs. 3 and 5. A hole or recess,

0, is cut or otherwise formed in the side of the frame to receive the rollers. A spring,

25, is secured to the face of the side piece, A. and is curved into the opening 0 in thesaid side piece, and grasps in its free end the common axle z of the rollers 1', which thus lie on either side of the spring. The tendency of the spring is to throw the rollers out. A strip, k, is secured to side piece, A, along the edge of the latter, and extends beyond the sides of piece A, (see Figs. 3 and 5,) as shown 7 in Fig. 5, and in that slide Aof Fig. 3 which is uppermost in said Fig. 3. The edges of this metal guide plate or strip it projecting beyond the sides of the piece A pass behind and engage withthe plates or diaphragms k to hold the side pieces, A, in proper position. \Vhen in posit-ion, the rollers 1', forced out by the spring it, pass against the rear side or face of groove f and in this way draw the plate or strip in snugly against the plate It. It may be here remarked that'usually two plates k are to be employed on each sliding piece A,

one of said plates being located near the top of the sliding piece and the other plate near the bottom 'of said sliding piece.

I preferably provide each slide-piece A with two sets of frictiolrrollers, one at the top and the other at the bottom; but more may be provided, if deemed desirable.

The groove n is the space in which the cord 9 5 of the counterbalancing-weight runs. This space may, when preferred, be in the slidepiece A.

The sashcord and pulley constitute the most satisfactory mode of hanging my im- 1C0 proved windows; but the old method of window catches can be applied to this form of sash as readily as to the old form.

While the bevel of the sides of the strips B is desirable as an additional guide and retaining device for the pieces A, it may be dispensed with without materially altering the operation of the sliding pieces A.

The spring 1. may be varied in shape, as may also the roller or rollers r.

The sash proper or frame, a, which incloses the pane of glass it, is arranged to swing on one of the side pieces, A, as shown in Fig. 1. This may be accomplished by the aid of a simple hinge at the joint; but where there are side shutters such a means would not be as desirable as certain other forms of hinges.

A preferred description of hinge to be em ployed when inside shutters are present consists in a suit-able extensible hinge of any suitable construction.

A useful hinge of the class of extensible hinges, and convenient for use, will now be de scribed. In place of the simple hinge I use lazy-tongs, either a single pair extending from the top to the bottom of the sash,or,preferabl y, two smaller pairs-one near the top and immediately below the spring 16, and the other at the bottom, immediately above the rollers and spring there present. The preferred construction and connections of these lazy-tongs are shown in Fig. 4. Two side plates, d, are screwed or otherwise fastened to the parts of the sash, one to that side of frame A which is adjacent to sash a, the other to that side of sash a which is adjacent to its neighboring frame A. From the upper portion of each plate (I a tongue, projects, from which a pin, 0, extends downwardly, terminating in an enlarged and preferably ball'shaped end. On the lower end of each side piece, (I, is a guide, 0. From each of the pins 0 above an arm, 0, hangs down and is attached to the guide a on the opposite side. Each end of each of the arms 0 terminates in loops or rings, the upper rings or loops surrounding the pins 0 but not large enough to slip over the ends of the pins, where they form a sort of pivot or ball-and-socket 5 joint. One of the guides 0 passes through the lower ends of one of the arms 0, and the other guide 0 passes through the lower end of the other arm 0, and the arms slide up and down on their said respective guides. The arms 0 at their center are united by the pivot 0 The lazy-tongs joint at the upper end of the sliding piece A is preferably in the position shown in Fig. 4; but the lazy-tongs joint'at the bot tom of the sliding piece A is preferably reversed in position-that is to say, the guides c c are uppermost and the pins 0 and pins 0 are underneath. This tends to steady the sash and the better prevent it from sagging when drawn out from side A. It is readily seen that this arrangement makes a hinge on which the frame a may be swung. Moreover, after the frame has been swung into the room it can be pulled or drawn farther in, so that it will clear the inside shutters. This is accomplished by the lazy-tongs spreading and sliding upon the grooves c. This arrangement is of especial advantage in the upper sash,

which slides in the outer groove. It is of great advantage, as it practically admits the window to be drawn entirely into the room, and thus makes the cleaning of it a safe and easy process.

To enable a vertical movement communicated to the sash to be communicated in turn to that side frame A which is not hinged to sash-frame a when the sash a is closed, I provide a suitable device, a preferred form of such device being as follows: Small recesses c on the free edge of frame a fit over the pins or flanges e, which appear on the adjacent frame A, or vice versa. These support the weight of the sash at this point. It is kept closed by any convenient device, as a belt or hook, or a button, a, as shown in Fig. 1.

To better prevent the frame a, when being shut, from passing that frame A adjacent to the free edge of sash-frame a, I preferably provide a bead or vertical shoulder or stop, 20, on said frame A. Against this stop the sashframe a rests when shut, and the bottom or equivalent catch, a, being removed, secures the sash-frame a from moving inward, and stop w seen-res it from moving outward. Thus we have a window which slides easily up and down in ways, presenting much less friction than common. At the same time it allows the sash to be opened into the room, a maneuver desirable, not only desirable for the purpose of cleaning, but also'for other purposes.

The various features of my invention are preferably employed together; but one or more of said features may be used without the remainder. In so far as applicable, one or more of said features maybe employed with window devices other than those specifically herein set forth.

That I claim as new and of my invention, and desire to secure by Letters Patent, is

1. The combination of the side pieces, A, each sliding in and secured to the windowframe, and the sash a, pivoted for swinging laterally away from one side of the windowframe and extensible laterally therefrom, su bstantially as and for the purposes specified.
